Clinical Trial Summary

AML and MDS-EB2 are malignancies of the bone marrow. The standard treatment for these diseases is chemotherapy. Patients participating have a special type of this disease because the leukemia cells (blasts) have developed an error in the genetic material (DNA). This error is called an IDH1 mutation or an IDH2 mutation (a mutation is a change in the DNA), which leads to changes in specific substances in the leukemia cells. This trial will investigate whether the addition of the new drugs Ivosidenib (for patients with IDH1 mutation) or Enasidenib (for patients with IDH2 mutation) to the standard treatment of chemotherapy controle the disease more effectively and for a longer period.

• Enrollment: 968
• Est. completion date: March 2033
• Est. primary completion date: March 2023
• Accepts healthy volunteers: No
• Gender: All
• Age group: 18 Years and older

Eligibility

Inclusion Criteria:

• Age =18 years
• Newly diagnosed AML or MDS-EB2 defined according to WHO criteria, with a documented IDH1 or IDH2 gene mutation (as determined by the clinical trial assay) at a specific site (IDH1 R132, IDH2 R140, IDH2 R172). AML may be secondary to prior hematological disorders, including MDS, and/or therapy-related (in which prior disease should have been documented to have existed for at least 3 months). Patients may have had previous treatment with hypomethylating agents (HMAs) for MDS. HMAs have to be stopped at least four weeks before registration
• Patients with dual mutant FLT3 and IDH1 or IDH2 mutations may be enrolled only if, for medical or other reasons, treatment with a FLT3 inhibitor is not considered.
• Considered to be eligible for intensive chemotherapy.
• ECOG/WHO performance status = 2
• Adequate hepatic function as evidenced by:
• Serum total bilirubin = 2.5 × upper limit of normal (ULN) unless considered due to Gilbert's disease (e.g. a mutation in UGT1A1) (only for patients in IDH2 cohort), or leukemic involvement of the liver - following written approval by the (Co)Principal Investigator.
• Aspartate aminotransferase (AST), alanine aminotransferase (ALT), and alkaline phosphatase (ALP) = 3.0 × ULN, unless considered due to leukemic involvement of the liver, following written approval by the Principal Investigator.
• Adequate renal function as evidenced by creatinine clearance > 40 mL/min based on the Cockroft-Gault formula for glomerular filtration rate (GFR).
• Able to understand and willing to sign an informed consent form (ICF).
• Written informed consent Female patient must either: o Be of nonchildbearing potential: Postmenopausal (defined as at least 1 year without any menses) prior to screening, or Documented surgically sterile or status posthysterectomy (at least 1 month prior to screening) o Or, if of childbearing potential: Agree not to try to become pregnant during the study and for 6 months after the final study drug administration And have a negative urine or serum pregnancy test at screening And, if heterosexually active, agree to consistently use highly effective* contraception per locally accepted standards in addition to a barrier method starting at screening and throughout the study period and for 6 months after the final study drug administration.
• Highly effective forms of birth control include:
• Consistent and correct usage of established hormonal contraceptives that inhibit ovulation,
• Established intrauterine device (IUD) or intrauterine system (IUS),
• Bilateral tubal occlusion,
• Vasectomy (A vasectomy is a highly effective contraception method provided the absence of sperm has been confirmed. If not, an additional highly effective method of contraception should be used.)
• Male is sterile due to a bilateral orchiectomy.
• Sexual abstinence is considered a highly effective method only if defined as refraining from heterosexual activity during the entire period of risk associated with the study drug. The reliability of sexual abstinence needs to be evaluated in relation to the duration of the clinical study and the preferred and usual lifestyle of the patient.
• List is not all inclusive. Prior to enrollment, the investigator is responsible for confirming patient will utilize highly effective forms of birth control per the requirements of the CTFG Guidance document 'Recommendations related to contraception and pregnancy testing in clinical trials', September 2014 (and any updates thereof) during the protocol defined period.
• Female patient must agree not to breastfeed starting at screening and throughout the study period, and for 2 months and 1 week after the final study drug administration.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Event-free survival (EFS)	EFS is defined as the time from randomization to failure to achieve CR or CRi after remission induction, death after achieving CR or CRi or relapse after achieving CR or CRi, whichever occurs first. A patient is said to have failed to achieve CR or CRi after induction therapy, if his/her best response during or at completion of the induction treatment is less than CRi. Patients who achieved CR/CRi after remission induction and are not known to have relapsed or died will be censored at the date of last clinical assessment.	Approximately up to 60 months following first patient enrollment
Secondary	Overall survival (OS)	OS is defined as the time from date of randomization to date of death due to any cause. Patients still alive or lost to follow up will be censored at the time they were last known to be alive.	Approximately up to 84 months following first patient enrollment
Secondary	Relapse-free survival (RFS) after CR/CRi	RFS is defined as time from the date of achievement of CR/CRi until relapse or death from any cause, whichever comes first. Patients still in first CR/CRi and alive or lost to follow up will be censored at the date of last clinical assessment.	Approximately up to 60 months following first patient enrollment
Secondary	Cumulative incidence of relapse (CIR) after CR/CRi	CIR is measured from the date of achievement of CR/CRi until the date of relapse. Patients not known to have relapsed will be censored on the date of last clinical assessment. Patients who died without relapse will be counted as a competing cause of failure.	Approximately up to 60 months following first patient enrollment
Secondary	Cumulative incidence of death (CID) after CR/CRi	CID is measured from the date of achievement of CR/CRi until the date of death from any cause. Patients not known to have died will be censored on the date they were last known to be alive. Patients who experienced relapse in CR/CRi will be counted as competing cause of failure.	Approximately up to 60 months following first patient enrollment
Secondary	Complete remission without minimal residual disease (CRMRD-) rate after induction cycle 2	CRMRD- rate is defined as the percentage of patients who achieved CR or CRi with no evidence of MRD in bone marrow	Approximately up to 60 months following first patient enrollment
Secondary	Frequency and severity of adverse events according to CTCAE version 5.0	Adverse events will be evaluated using the National Cancer Institute's Common Terminology Criteria for AEs (CTCAE) version 5.0	Continuously throughout the study, starting from informed consent until 30 days following the last administration of any study drug
Secondary	CR/CRi rates after induction cycle 1 and 2	CR and CRi are determined by the Investigator based on the European LeukemiaNet (ELN2017) recommended response criteria	Approximately up to 60 months following first patient enrollment
Secondary	CR/CRi rate after remission induction (i.e., CR or CRi as best response during or at completion of induction therapy)	CR+CRi rate after remission induction is defined as the percentage of patients with best response of CR or CRi during or at completion of induction therapy	Approximately up to 60 months following first patient enrollment
Secondary	Time to hematopoietic recovery after each chemotherapy treatment cycle	Time to hematopoietic recovery is defined as the time from the start of the cycle until recovery	Approximately up to 60 months following first patient enrollment
Secondary	EQ-5D-5L visual analogue scale (VAS)	The EQ-5D-5L is a 5 item questionnaire that assesses 5 domains including mobility, self-care, usual activities, pain/discomfort and anxiety/depression plus a visual analog scale rating "health today". Each domain has 5 levels. Each level has a 1 digit number expressing the level selected for that dimension. These levels are summed up and the self-rated health is recorded on a 20 cm vertical, visual analogue scale, with endpoints labelled 'the best health you can imagine' and 'the worst health you can imagine'.	At entry, 1st day of maintenance, every 3 months during the first year of maintenance, every 6 months during the second year of maintenance until relapse or treatment discontinuation (approximately up to 84 months following first patient enrollment)
Secondary	EORTC-QLQ-C30 global health status/QoL scale.	The EORTC QLQ-C30 is a 30-item questionnaire that assesses 5 functional subdomains (physical functioning, role functioning, emotional functioning, cognitive functioning and social functioning), 1 global health status, 3 symptom subdomains (fatigue, nausea and vomiting and pain) and 6 single items (dyspnea, insomnia, appetite loss, constipation, diarrhea, and financial difficulties). All of the scales and single-item measures range in score from 0 to 100. A high scale score represents a higher response level. Estimate the average of the items that contribute to the scale; this is the raw score. a higher score represents a higher ("better") level of functioning, or a higher ("worse") level of symptoms.	At entry, 1st day of maintenance, every 3 months during the first year of maintenance, every 6 months during the second year of maintenance until relapse or treatment discontinuation (approximately up to 84 months following first patient enrollment)
